To ALL WHOM m. MAY 00mm,

Be it known that I, DE VVLTT S. RAWSON, of the city of Porn, in thecounty of La Salle, and State of Illinois, have invented a new andimproved Stereoscopic View Box; and I do hereby declare the following tobe a full and exact dcscrihtion thereof, reioronco being had to theaccompanying drawings and letters of rofcrence marked thereon.

The object of my invention is to produce a stereoscopic instrument, inconnection with the packing-box for pictures, in such a manner that whenopened out several pictures may be viewed in succession without theusual handling of each picture, and when closed the views and instrumentwill be contained in the same package. In order to accomplish this,Iprepnro a box, A, about eight inches in length-and about five inches inwidth and depth, the picture-box H, occupying about one-half of the box,being at the bottom. The cover 13 of said box A; is hinged about oneinch back of the middle, and on its inner side are attached stereoscopiclenses 0, arranged in any of the usual forms, and. hanging upon a pivotso in one position it will close down into the box, but when opened andturned outit will extend beyond the cover The front D is attached toabout one-third of the bottom, and with it forms a-right angle, and ismade to turn on pivots near the lower front corners; near the middle ofsaid front isthc picture shelf or brackets E .i, upon which severalpictures may at onetime be placed. The object of the movable front is tothrow the pictures when placed thereonout of a perpendicular, so as tokeep them in position, and also thatthey may stand at nearly rightangles with the line ofgvisiou of the lenses when in position, and alsoto assist in obtaining the focus by being moved back and forward asoccasion may require, 7

The manner of operatingsaid instrument is to open and turn back thecover B sons to stand at an angle of about forty degrees, then swing thefront forward to stand at nearly a right angle with the cover, -when itwill be found that the portion of the bottom attached to the front hasraised the fronts of the views to a position easily grasped by the hand,when they may be placed on the brackets E D; the lenses may then heturned in position to view the pictures and place the eyes to thepicture in the usual manner. With the right hand the movable front mayhe moved to adjust the focus, when it is desired to change the view;with the right fore-fingeron the top of it, tip it forward till'it willfall into the picture-box H, when its successors may be viewed andtreated in the some manner.

What I claim as my invention, and desire to secure by Letters Patent, is

The picture-box H, the swinging front I), and shelves or brackotsll E,substantially as herein described.
